We've seen some reports that Daily Mix has completely disappeared from Your Library.
We're looking into it!
Thanks for the reports. We've noticed a couple of different experiences here, and we'd like to clear up any confusion!
If you've noticed that one of your 6 Daily Mixes has disappeared, then it's likely nothing to worry about!
The feature analyzes your music listening history and creates 1-6 mixes depending on the amount and diversity of your listening. If you stop listening to a selection of music, then the corresponding Daily Mix could disappear. Don't worry! If you start to listen to those songs again, it should come back in about 2 weeks. You can learn more about Daily Mix on our support site.
If your whole Daily Mix section has disappeared from Your Library, then let us know by adding your +VOTE add the of this thread!
We'll continue to investigate this with the tech team.
